USING THE 105SX
MENU FUNCTIONS
Depth Alarm. The 105SX contains
an audible alarm to warn you of
shallow water depths. The alarm is
adjustable to depths of 3' to 99'
(30m). When the alarm is enabled,
an audible alarm sounds if the water
beneath the boat is equal to or less
than the selected alarm depth. The
alarm sounds continuously for about
five seconds, and then intermittently
to remind you that you are still in
shallow water.
Fish Alarm. The Fish Alarm alerts
you to the presence of fish, or other
targets not connected to the
bottom. The Fish Alarm has three
different settings that correspond to
the three different size fish symbols
shown on-screen.
The default setting is "OFF." With
the "Large fish only" setting, the
105SX alarms on only those targets
that are represented by the large
fish symbols. The 105SX can be set
to alarm on only large and medium
fish, or set to alarm on all fish.
Set for large fish only
Once the Fish Alarm is
Set for large and medium fish
enabled, the 105SX emits an
Set for all fish
audible beep when the
selected size fish symbol appears on-screen.
